RELATED APPLICATIONS

This application is a national phase entry of International Application No. PCT/EP2017/072237 filed on Sep. 5, 2017 and published in the English language, which claims the benefit of U.S. Provisional Application No. 62/383,716 filed Sep. 6, 2016, both of which are hereby incorporated by reference.

TECHNICAL FIELD

The present invention relates generally to solutions for enabling secure communication of patient data.

More particularly, the invention relates to a method for enabling secure communication of patient data according to the preamble of claim 1, and corresponding system. The invention also relates to a computer program and a non-volatile data carrier.

BACKGROUND

Healthcare is used as an example of an owner of a host application in the text below. The owner of the host application could be any party or organization that could have an interested in an individual's/patient's registered health data. The health data is represented as quantitative data such as number of steps, weight, electrocardiography measures, spirometer measures, blood pressure, degree of patient's perceptive of pain etc. or qualitative data which is the individual's perception written in free text format.

The party and/or organisation having interest in the individual's registered quantitative or qualitative data described could be public or private healthcare, academic research projects, industry research projects, public/private registries, qualitative registries, bio banks, health authorities etc. The data might also be retrieved on a consent basis for follow-up of the sale of consumer goods for functionality or quality checks and for customer satisfaction screening or for direct marketing purposes. Another party having interest in the individual's registered quantitative or qualitative data could be the pharmaceutical industry.

When we refer to the patient's “app”, or “patient application”, this includes the Patient Connector (PC) and also the patient's unit/device/client that the app is implemented in. When we refer to the caregiver's “host application” this includes the Patient Connector (“PC”) and also the caregiver's server/unit/system.

Transfer of data means that information is sent via a message between the app in the patient's device and the host application on healthcare's server.

A Software Development Kit (“SDK”) is a component/set of software development tools that allows the creation of applications for a certain software package, software framework, patient application, electronic health record, research system or other applications and systems.

DESCRIPTION OF THE FIGURES

The invention is now to be explained more closely by means of preferred embodiments, which are disclosed as examples, and with reference to the attached drawings.

FIG. 1 shows an overview of a system according to one or more embodiments of the invention;

FIG. 2 shows a flow diagram illustrating a process for secure communication of digital information, comprising steps according to one or more embodiments of the proposed method;

FIG. 3 shows a flow diagram illustrating one or more embodiments of the proposed method;

FIG. 4 shows a flow diagram illustrating a process for secure communication of digital information, comprising steps according to one or more embodiments of the proposed method.

DESCRIPTION OF THE INVENTION

The subject invention provides secure communication by transferring information that does not include personal or individual identification information so as to keep the identity of the information provider(s) confidential during the transfer of information. The patient's app and the host application will pair through the PC by utilizing a randomized generated code that is unique for the subject patient. The randomized code is transferred into an ID/access key in the patient app that is known to the host application. The ID/access key is matched with a stored hash in the host application to identify the information provider.

In other words, embodiments presented herein enable secure communication of confidential and sensitive patient data, even via open, wireless networks such as the Internet, because the patient data is completely anonymous during the transfer from the patient application (patient's app) to the host application. This is essential because there are strict regulations controlling handling of sensitive patient data that need to be fulfilled. For instance, embodiments presented herein aim at fulfilling the EU General Data Protection Regulation (GDPR).

In addition to this, embodiments presented herein further enable the host application, e.g. a healthcare provider/care giver to accurately associate the patient data with the correct patient's identity after the patient data has been received from the patient application. This is also essential, as the medical data sent by the patient is useless to the healthcare provider/caregiver if it cannot be established without a doubt with which patient the received patient data is associated. Not to mention that if it cannot be established without a doubt with which patient the received patient data is associated, patient security would be jeopardized due to risk of providing the wrong treatment to the wrong patient, or not providing treatment to a patient in need of it, e.g.

The invention provides a solution to the technical problem of transferring securely sensitive information over the internet or through other information networks. The subject invention realizes the solution by providing means and methods of sending such information unidentified and without personal identity information and pairing the unidentified information at the reception by the host with the identity information in the ID/access key. There was prior to the invention no solution to the challenge of sending unidentified patient data over the Internet and still be able to connect securely patient registered data in a patient app to a host application, e.g. a health care decision support system, electronic healthcare record, or a research institution's information system or any other health or biotech related registry. Within the context of the present disclosure, patient registered data may be replaced with, or complemented by, patient generated data, without any modifications of the method and system embodiments being necessary. Current host systems are unable to tell with acceptable certainty what information belongs to which patient without accommodating patient identity information during the transfer of information. For applications where patients are transferring patient registered data to a health care provider for diagnosing or health care follow-up there is a need of un-identification, security and accuracy mechanisms when transferring data. The suggested invention resolves this problem by pairing the patient app and the host application during a meeting in person between the patient and for instance a medical professional from healthcare. Alternatively, the meeting could be with a person conducting a pharmaceutical research project. In relation to this meeting the patient has securely identified herself at the registration desk at a department in a hospital and the medical professional has identified herself, with so called strong authentication, when logging into the host application. The procedures of identification/authentication meet required degrees of security and accuracy.

As an alternative, also the patient identifies herself, using so called strong authentication, when logging into the patient application or using another system provided by the medical professional from healthcare. Also in this case, the procedures of identification/authentication meet required degrees of security and accuracy.

Furthermore, in connection with performing the pairing of applications, the patient knowingly consents to the host application, and in turn the host (medical staff, caregiver or other actor as described herein), having access to the patient data that is anonymously communicated from the patient application to the host application, and further having access to information uniquely identifying the patient associated with the patient data. According to embodiments described herein in connection with the figures, each time patient data is to be sent from the patient application and also each time identification is to be performed in the host application, a check is performed to determine whether a pairing exists between the host application and the patient application. In other words, the patient consent is checked every time. If the patient should for some reason no longer consent to sharing her patient data and identification data, the patient may delete the patient application from her smartphone or other user device where the patient application has been installed. Thereby, when the next check is performed, in step 240 or 280 in connection with FIG. 2, no pairing is found and the method ends. Thereby, a required degree of security is obtained to e.g. fulfill GDPR and other relevant legal regulations.

In FIG. 1, embodiments of a healthcare monitoring system 100 for anonymous communication of patient data D, associated with a patient P, from an electronic user device to a host server, via a wireless network, and identification of the patient P associated with the patient data D after the patient data D is received in the host server, are shown.

According to one or more embodiments, the healthcare monitoring system 100 comprises an electronic user device 120, which comprises a patient application 110; and a host server 140, which comprises a host application 130. The patient application 110 is configured to communicate with the host application 130 via a wireless network 180. The system 100 further comprises a memory 150 accessible by the patient application 110 and a memory 160 accessible by the host application 130. In one or more embodiment, the system 100 is configured to pair the patient application 110 and the host application 130. This is achieved by the host application being configured to i) generate a unique access key K for the patient P, wherein the unique access key K is unrelated to any information identifying the patient P, wherein the unique access key K comprises a first part K_1 and a second part K_2; ii) store the second part K_2 of the unique access key K in the memory 160 accessible by the host application 130, wherein the second part K_2 is stored in association with information identifying the patient P; and iii) send the first part K_1 of the unique access key K to the patient application 110; whereby the patient application 110 is configured to i) receive first part K_1 of the unique access key K from the host application 130; ii) store the received first part K_1 of the unique access key K in the memory 150 accessible by the patient application 110; iii) receive patient data D, from at least one patient data registering device 170; and iv) in response to receiving patient data D in the patient application 110, send the received patient data D and the first part of the access key K_1 to the host application 130. The host application 130 is further configured to: i) receive patient data D and the first part of the access key K_1 from the patient application 100; and ii) identify the patient P associated with the received patient data D, based on the received second part K_2 of the access key K. Thereby, the patient data D is anonymous and secure when it is sent via the wireless network, but is uniquely identified as being associated with the patient P after it is received in the host application.

The host application 130 may be configured to authenticate a caregiver as an authorized user of the host application 130, using strong authentication, prior to the pairing of the patient application 110 and the host application 130.

In some embodiments, the patient application 110 is configured to authenticate a patient P as an authorized user of the patient application 110, using strong authentication, prior to the pairing of the patient application 110 and the host application 130.

In some embodiments, the host application 130 is configured to identify the patient P associated with the received patient data D, based on the second part K_2 of the access key K, by: i) generating a second part K_2 of the access key K, based on the received first part K_1 of the access key K; ii) comparing the generated second part K_2 of the access key K to one or more second parts of access keys stored in the memory 160 accessible to the host application 130 to find a matching second part, wherein the stored one or more second parts of access keys have been generated during pairing of the host application 150 with one or more patient applications 110; and iii) if a matching second part of an access key is found, identifying the patient P as the patient associated with the matching second part stored in the memory 160.

In one or more embodiments, generating a unique access key K for the patient P is enabled by the host application 130 being configured to generate a randomized numeric code C that is unrelated to any information identifying the patient P; the patient application 110 being configured to receive the randomized numeric code C from the host application 130 and send a message in the form of a control signal S1 to the host application 130 in response to receiving the unique access key K; and the host application 130 being configured to receive the control signal S1 from the patient application 110 and generate the unique access key K in response to receiving the control signal S1.

The healthcare monitoring system 100 comprises or is connected to a memory 150 accessible to the patient application 110. The healthcare monitoring system 100 further comprises or is connected to a memory 160 accessible to the host application 130. In FIG. 1, memory 150 is illustrated as being part of the patient application 110 and memory 160 is illustrated as being part of the host application 130. However, the memory 150 may be integrated in, connected to, or communicatively coupled to the patient application 110, and the memory 160 may be integrated in, connected to, or communicatively coupled to the host application 130.

FIG. 2 shows a flow diagram illustrating one or more embodiments of a method/process in a healthcare monitoring system 100 for anonymous communication of patient data D, associated with a patient P, from an electronic user device 120, using a patient application 110 implemented in the electronic user device 120, to a host server 140, using a host application 130 implemented in the host server 140, via a wireless network 180, and further for identification of the patient P, associated with the patient data D, after the patient data D is received in the host server 140.

According to one or more embodiments illustrated by FIG. 2, the method comprises:

In step 200: Pairing the patient application 110 and the host application 130.

Of course, a host application 130 can be paired with one or more patient applications 110, for receiving patient data from corresponding one or more patients.

In an optional step 210: Checking if the pairing in step 200 was successful.

According to embodiments wherein the method step 210 of checking whether the pairing in step 200 was successful is performed:

-   -   if the pairing was not successful, the method returns to step         200 to allow for another, optional, paring attempt; or     -   if the pairing was successful, the method continues according to         step 220 and step 260, respectively.

Steps 220-250 below describe the method steps performed by the patient application 110, and steps 260-290 describe the method steps performed by the host application 130.

In one or more embodiments, the patient application 110 is configured to perform any or all of the method steps 220-250.

In one or more embodiments, the host application 130 is configured to perform any or all of the method steps 220-250.

In an optional step 220: Checking whether patient data D has been registered.

The patient data D may have been registered by at least one patient data registering device 170, wherein the at least one patient data registering device 170 may comprise a selection of the following: one or more sensors for blood pressure rate, heart rate, breath rate, ECG/EKG (electro-cardiogram), respirations, blood oxygen levels, blood temperature, spirometer, or medtech equipment (ultra sound, patient monitor anesthesia, X-Ray mobile, oxygen concentrator, coagulometer, scale for adults, CT-scanner, one or more digital forms, or applications such as e.g. Health Kit or Google Fit.

According to embodiments wherein the method step 220 of checking whether patient data D has been registered is performed:

-   -   if no patient data D has been registered, the method returns to         step 220; or     -   if patient data D has been registered, the method continues         according to step 230.

In step 230: Receiving, in the patient application 110, patient data D from at least one patient data registering device 170.

Receiving patient data D may also be referred to as new relevant data being generated in the patient application 110.

In an optional step 240: Checking whether a pairing exists between the patient application 110 and the host application 130.

Reasons that a pairing may no longer exist are e.g. that: pairing between the host application 130 and patient application 110 has been terminated either by the patient P deleting the patient application 110 from her smartphone or other user device where the patient application 110 has been installed; the healthcare provider deleting the patient in the host application 130 by deleting the second part K_2 (e.g. the hash) of the unique access key K that is related to/associated with the patient identifying information; or due to an error.

According to embodiments wherein the method step 210 of checking whether a pairing exists between the patient application 110 and the host application 130:

-   -   if no pairing exists, the method ends and no further patient         data D is communicated from the patient application 110 to the         host application 130; or     -   if a pairing exists, the method continues according to step 250.

In step 250: Sending the received patient data D and the first part K_1 of the access key K to the host application 130.

Sending the received patient data D and the first part K_1 of the access key K to the host application 130 is done in response to receiving patient data D in the patient application 110.

As mentioned in connection with FIG. 4, information is hereafter securely and automatically transferred, according to the patient application 110 configuration, between the patient application 110 and the host application 130. According to different settings or configurations of the patient application 110, patient data D may be sent/transferred to the host application 130 continuously, at certain time intervals, only at certain times, e.g. only at night, or according to any other suitable rules/configuration depending on the circumstances.

In an optional step 260: Checking whether patient data D has been sent.

According to embodiments wherein the method step 260 of checking whether patient data D has been sent is performed:

-   -   if patient data D has not been sent, the method repeats step         260; or     -   if patient data D has been sent, the method continues according         to step 270.

In step 270: Receiving in the host application 130 the patient data D and the first part K_1 of the access key K.

In step an optional step 280: Checking whether a pairing exists between the patient application 110 and the host application 130.

According to embodiments wherein the method step 280 of checking whether a pairing exists between the patient application 110 and the host application 130:

-   -   if no pairing exists, the method ends; or     -   if a pairing exists, the method continues according to step 290.

In step 290: Identifying the patient P associated with the received patient data D, based on the second part of the access key K.

In one or more embodiments, the pairing of step 200 comprises sub-steps 310-340, wherein:

In sub-step 310: Generating a unique access key K for the patient P, using the host application 130, wherein the unique access key K is in itself unrelated to any information identifying the patient P, wherein the unique access key K comprises a first part K_1 and a second part K_2.

Sub-step 310 of generating a unique access key K for the patient P may in turn comprise:

-   -   generating, using the host application 130, a randomized numeric         code C that is unrelated to any information identifying the         patient P;     -   receiving, in the patient application 110, the randomized         numeric code C;     -   sending a message in the form of a control signal S1 from the         patient application 110 to the host application 130 in response         to receiving the unique access key K;     -   receiving, in the host application 130, the control signal S1;         and     -   generating, in the host application 130, the unique access key K         in response to receiving the control signal S1.

The randomized numeric code C may be received in the patient application 110 in response to a user, i.e. the patient P, registering/inputting the code using one or more input devices (not shown in the figure) that is/are integrated in, connected to or communicatively coupled to the electronic user device 120. The one or more input devices may e.g. be in the form of a keyboard, touch functionality, speech to text functionality, or any other suitable input device known in the art. According to different embodiments, the randomized numeric code C may, before it is input into the patient application 110, be communicated to the patient P orally by the medical staff/caregiver/host, or sent as a digital signal from the host application 130 to the patient application 110, using any suitable communication protocol and communication method known in the art. As non-limiting examples, the randomized numeric code C could be sent in the form of a short message service (SMS), e-mail, or a message in the patient application interface.

Method step 310 may further comprise, and the host application 130 may further be configured to, setting/configuring the numbers of digits in the randomized numeric code C and/or the length of time of validation of the randomized numeric code C.

In sub-step 320: Storing the second part K_2 of the unique access key K in a memory 160 accessible to the host application 130, wherein the second part K_2 is stored in association with information identifying the patient P.

In sub-step 330: Sending the first part K_1 of the unique access key K from the host application 130 to the patient application 110.

In sub-step 340: Storing the first part K_1 of the unique access key K in a memory 150 accessible to the patient application 110.

In some embodiments, identifying the patient P associated with the received patient data D, based on the second part K_2 of the access key K comprises:

-   -   generating a second part K_2 of the access key K, based on the         received first part K_1 of the access key K;     -   comparing the generated second part K_2 of the access key K to         one or more second parts of access keys stored in the memory 160         accessible to the host application 130 to find a matching second         part, wherein the stored one or more second parts of access keys         have been generated during pairing of the host application 130         with one or more patient applications 110; and     -   if a matching second part of an access key is found, identifying         the patient P as the patient associated with the matching second         part stored in the memory (160).

A substantial advantage of using a unique access key K that is unrelated to any information identifying the patient P, is that the access key K, or any of its parts K_1 and K_2, cannot by themselves be linked to the patient P. Should the patient data D fall into the hands of someone other than the intended user of the host application or host server, the patient's identity is thereby protected.

In one or more embodiments, the first part K_1 of the unique access key K is the original key and the second part K_2 of the unique access key K is a hash or thumbprint of the original key.

The method may comprise, to generate the second part K_2 of the access key K based on the received first part K_1 of the access key K, running a mathematical function on the first part K_1.

The host application 130 may correspondingly be configured to run a mathematical function on a first part K_1 of a unique access key K to generate a second part K_2 of the unique access key K.

The method according to any of the embodiments presented herein may further comprise, prior to pairing the patient application 110 and the host application 130:

-   -   authenticating a caregiver as an authorized user of the host         application 130, using strong authentication; and     -   authenticating a patient as an authorized user of the patient         application 130, using strong authentication.

Authenticating the caregiver may be performed using the host application 130, e.g. during login.

Authenticating the patient P may be performed using a patient application 110, e.g. during login. Alternatively, authenticating the patient P may be performed by identifying the patient P at the check-in desk in a hospital or the like, by using a driver's license, passport or similar.

The method according to any of the embodiments presented herein may further comprise storing the received patient data D in the memory 150 accessible to the patient application 110.

FIG. 4 shows a flow diagram illustrating a process for secure communication of digital information, comprising steps according to one or more embodiments of the proposed method. The patient in the description of FIG. 4 below corresponds to the patient P.

The process of applying secure communication by transferring information that does not include personal or individual identity information consist of a number of steps.

Below, the process of secure communication illustrated in FIG. 4 is described in more detail:

1. The PC is imported both into the caregiver's host application and into the patient's app. Referring to the reference numbers in FIG. 4, this is step 1.

2. The PC is customized in the host application

-   -   a. Configuring the numbers of digits in the randomized code     -   b. Length of time of validation of the randomized code

Referring to the reference numbers in FIG. 4, this is step 2.

3. In the patient's app it is configured when information should be transferred between the patient app and host application. Referring to the reference numbers in FIG. 4, this is step 3.

4. Identification

-   -   a. The patient is securely identified at the check-in desk in a         hospital by using a driver's license or similar identification.     -   b. The medical staff is securely identified via login using         strong authentication in the host application.

Referring to the reference numbers in FIG. 4, this is step 4. As can be seen from step 4 in FIG. 4, the identification of the patient can be performed e.g. in the hospital reception. Further applicable options are presented in connection with FIG. 2.

5. The medical staff asks the patient to download the patient app in her smartphone during the physical meeting

6. The medical staff asks the patient to open the patient app in her smartphone during the physical meeting. Referring to the reference numbers in FIG. 4, this is part of step 5. 7. The medical staff generates a randomized set of numbers (i.e. a random code) for the specific patient attending the physical meeting in the host application. The host application generates the randomized set of numbers through the imported PC. Referring to the reference numbers in FIG. 4, this is part of step 6. This corresponds to generating the randomized numeric code C according to embodiments presented herein.

8. The medical staff forwards the given randomized set of numbers orally to the patient during the meeting in person. Referring to the reference numbers in FIG. 4, this is part of step 6.

9. The patient records the randomized set of numbers in the patient's app accessed through/installed in her smartphone during the meeting in person. Referring to the reference numbers in FIG. 4, this is step 7.

The randomized numeric code C may alternatively be communicated directly from the host application 130 and received in the patient application, according to embodiments presented herein.

10. A technical pairing is made between the caregiver's host application and the patient app. Referring to the reference numbers in FIG. 4, this is part of step 8. This corresponds to the pairing described in connection with FIG. 2.

11. Information is hereafter securely and automatically transferred according to the PC configuration between the patient's app and the caregiver's host application every time new relevant data is generated and stored in the patient's app. The message does not include any personal or individual identity information during the transfer of information over the Internet or any other network. Referring to the reference numbers in FIG. 4, this is part of step 8 and step 9.

12. The pairing between the host application and patient app is terminated when either:

-   -   a. The patient deletes the patient app from her smartphone     -   b. The healthcare provider deletes the patient in the host         application by deleting the hash that is related to the patient.         Referring to the reference numbers in FIG. 4, this is step 10.

Login into the patient app, by the patient, may include entering/inputting a password or other data that is unrelated to the patient's identity. This is preferable compared to using e.g. Bank ID or other methods that are linked to the patient's identity, and therefore potentially could be used to identify the patient who is using the patient app and sending her confidential patient data.

How the technical pairing between the caregiver's host application and the patient's app is conducted is described in more detail below:

i. The medical staff requests a randomized set of numbers for the identified patient in front of her in the host application.

ii. An ID is created in the host application for this specific patient. This ID is not based on a personal ID and cannot be linked to an individual's identity.

iii. When the randomized set of numbers, that has been given orally to the patient, is registered in the patient's app, the PC in the patient's app sends a message to the PC in the host application.

iv. When the host application receives the message the PC in the host application generates an access key that is sent to the patient app;

-   -   a. The access key is made up of two parts: a) an original key         that the patient app holds and b) a hash of the original key         that the host application holds.     -   b. The PC in the host application run a mathematical function on         the access key when received from the patient app. The         mathematical function generates the hash of the original key.

This access key corresponds to the unique access key K, having the two parts K_1 and K_2, according to embodiments presented herein.

v. A hash/thumbprint of the access key that has been is stored in the host application; (it is a hash/thumbprint of the access key sent to the patient app)

vi. Every time the patient's app transfer data to the host application the access key is accompanied/sent together with this transfer

vii. When the host application receives the message from the patient app the received accompanied access key is run through a mathematic function. The outcome from running the access key through mathematical function is this patient's hash.

viii. This hash/thumbnails is compared with the hashes stored in the host application to look up a match and the identification of the patient that has sent the data. This is an embodiment of how to identify the patient P associated with the received patient data D, based on the second part K_2 of the access key K, as described herein.

The patient connector is configured with anything from 1 to an infinite number of digits. Recommended is to provide with a random code consisting of at least 8 digits. To perform the pairing, the code is given by word of mouth from for instance a medical professional working in the host application to a patient.

The patient must to pair enter the numeric code into her client application in her smartphone. Alternatively, the numeric code is communicated directly from the host application 130 to the patient application according to any of the embodiments presented herein. The app client must call the host server code within a certain time, otherwise the code is invalid. The duration is set to 30 minutes, or any other suitable duration depending on circumstances.

The code is checked and if it is valid it is paired to the identity of a patient on the application and an access key is generated. This access key is returned to the patient app. A hash of the access key is stored on the host application; it is used to derive which patient it is that has communicated data from a patient app to the host application. The solution has thus achieved a connection between a patient app and a caregiver's host application. The access key itself does not contain any information about to whom the information sent belongs. Future connections between the patient's app and the caregiver's host application will use the same access key every time a transfer is made, enabling the host application to always know from which patient the data is sent.

The secure communication will advantageously be exercised in a computerized system and/or through the internet or any other network.

The PC will advantageously be utilized within any work in society that can benefit from continuous access to secure and accurate individual registered data.

In one or more embodiments, the patient application 110 and/or the host application 130 may be configured to perform any or all of the relevant method steps and functions presented herein.
